Abstract
The utility model relates to a refrigerant jetting noise reduction mechanism of a water chilling plant, which comprises a sealing cavity and a liquid taking pipeline. The refrigerant jetting noise reduction mechanism of the water chilling plant is characterized in that the sealing cavity is arranged on a side wall of a channel of a diffuser of a compressor, and the sealing cavity consists of a tank processed on the diffuser and a cover plate covered on the tank. The refrigerant jetting noise reduction mechanism of the water chilling plant utilizes pressure of a condenser and static pressure difference of the diffuser of the compressor, liquid refrigerant at the bottom of the condenser is led into the sealing cavity via a liquid taking pipeline, throttled and atomized via small holes on the cover plate, sprayed into the diffuser and mixed with high-temperature and high-pressure refrigerant gas in the diffuser, so that exhaust temperature and speed are reduced, friction loss of gas flow and a shell are greatly reduced, noise is reduced, and the refrigerant jetting noise reduction mechanism is quite favorable for reducing noise of unit utilization environments. In addition, the refrigerant jetting noise reduction mechanism of the water chilling plant can be widely applied to products of various centrifugal water chilling plants, screw stem type water chilling plants and the like.
Description
Technical field
The utility model relates to the noise reducing mechanism of handpiece Water Chilling Units, is specifically related to a kind of refrigerant injection noise reducing mechanism that is applicable to centrifugal, the screw-type water chiller of central air conditioning equipment.
Background technology
At present, known central air-conditioning refrigeration plant such as centrifugal, screw-type water chiller, because refrigerating capacity is big, its equipment noise generally reaches the 80-90 decibel, some equipment even up to 100 decibels, these equipment have also inevitably brought the various device noise when bringing comfortable air ambient, and the user has to these equipment is installed in specialized apparatus zones such as basement, but to equipment operative employee, administrative staff, its too high noise remains and is difficult to avoid.In order to address this problem, the noise reduction measure that adopts generally is to build soundproof room or at noise position parcel Sound-proof material at present.Wherein adopt involving great expense of soundproof room, floor space is big, is difficult for implementing; The employing Sound-proof material is economic and practical, but DeGrain generally can only reduce the 2-3 decibel.
Summary of the invention
The utility model provides a kind of refrigerant injection noise reducing mechanism that is used for handpiece Water Chilling Units, utilize the differential static pressure between condenser and the diffuser, the liquid refrigerant of condenser is sprayed into diffuser, reduce the temperature and the speed of refrigerant gas in the diffuser, fundamentally reduce exhaust noise.
The technical solution of the utility model is:
A kind of refrigerant injection noise reducing mechanism of handpiece Water Chilling Units, it comprises annular seal space, cover plate, O-ring seals and liquid flowing tube road; It is characterized in that: described annular seal space is arranged on the channel side wall of diffuser of compressor, annular seal space is by constituting at cell body of processing on the diffuser and the cover plate that covers on cell body, on the cover board evenly be furnished with throttling pore, the liquid refrigerant in the annular seal space forms fog-like liquid by throttling pore and sprays into diffuser; Adopt O-ring seals to seal between described cell body and the cover plate,, help atomizing effect to guarantee the flow and the pressure of refrigerant liquid by throttling pore; Described liquid flowing tube Lu Yiduan is connected with condenser, and liquid refrigerant is wherein drawn, and the other end is communicated with annular seal space by the passage of a valve on the diffuser sidewall.
The differential static pressure of this mechanism by diffuser and condenser causes annular seal space with the refrigerant liquid of condenser, and spray into diffuser by the throttling pore throttling on annular seal space cover plate atomizing, reduce the temperature and the flow velocity of the high temperature and high pressure gas in the diffuser, reduce noise, very favourable to the improvement of unit environment for use noise.This structure can be widely used in the products such as various centrifugal refrigerating machines, screw-type water chiller.
The utility model can reduce unit noise 6-10 decibel from the noise of root reduction unit, and effect is obvious, and cost is also low, because the little influence to refrigerating capacity of spouting liquid is also smaller.Therefore the utility model has important positive effect to improving the unit working environment.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A portion enlarged drawing of Fig. 1;
Among the figure: the 4-condenser 5-cover plate 6-O-ring seals 7-annular seal space 8-valve of 1-housing 2-diffuser 3-liquid flowing tube road.
The specific embodiment
Describe structure of the present utility model in detail below in conjunction with accompanying drawing:
Referring to Fig. 1, the refrigerant injection noise reducing mechanism of this centrifugal refrigerating machines comprises annular seal space 7 and liquid flowing tube road 3.Annular seal space 7 is arranged on the channel side wall of diffuser 2 of centrifugal compressor 1, by constituting at cell body of processing on the diffuser and the cover plate 5 that covers on cell body, adopt O-ring seals to seal between cell body and the cover plate 5, on the circumferential plane of cover plate 5, be evenly equipped with 6 throttling pore, within φ 2-φ 3.5, the liquid refrigerant in the annular seal space 7 forms fog-like liquid by throttling pore and sprays into diffuser 2 according to spouting liquid in the aperture.Liquid flowing tube road 3 one ends are connected with condenser 4, and liquid refrigerant is wherein drawn, and the other end is communicated with annular seal space 7 by the passage of a valve 8 on the diffuser sidewall.
This mechanism utilizes the pressure of condenser 4 and the differential static pressure between the compressor diffuser 2, cause in the annular seal space 7 by the liquid refrigerant of liquid flowing tube road condenser 4 bottoms, carry out the throttling atomizing by the aperture on the cover plate 5, spray into diffuser 2, mix with the high-temperature high-pressure refrigerant gas of diffuser 2 the insides, reduced delivery temperature and speed, the friction loss of air-flow and housing is significantly reduced, can reduce the noise 6-10 decibel of unit, among the figure arrow indication be liquid refrigerant gentle flow away to.
